If you add the early access repository into your SDK and have an older beta release of the SDK, you should see an update notification in the Sailfish OS IDE. Otherwise, you will see an update notification in the Sailfish OS IDE, when the Jolla Release 2.1.1 is publicly available to all users.

As before, in this update the build engine, emulator and targets are reinstalled so you will lose all changes you may have made in those - However, if your application packaging is done correctly, rebuilding your projects should reinstall the packages you have been using.

Any customization done to SDK (adding new package repositories, adding custom targets, additional source paths) will be removed during the installation process so make your own backup of those before starting the update.

If you import existing projects made with a previous version of the Sailfish OS SDK, make sure to select the correct kit in the project configuration step. Both ARM and i486 kits are available.

Package repository contents have been updated and consequently using a previous SDK version with these package repositories is not supported.
